Synthesis of a new C2-symmetric chiral diol: Application to asymmetric allylboration
摘要:
New C-2-symmetric chiral diol 1b was prepared from diol 3a, by a thionyl chloride mediated double elmination, hydrogenation and deprotection sequence. A comparative study of the asymmetric allylboration of benzaldehyde with the allylboronates 12 and 13 showed 15 and 18 % e.e. respectively in the corresponding homoallylic alcohol 14.
